The stats component displays a UI with performance-related metrics. The stats component applies only to the <a-scene> element.

Example

<a-scene stats></a-scene>

Metrics

• fps: frames per second, framerate. Aim for stable 90 fps with the WebVR 1.0 API.
• requestAnimationFrame (raf): Latency.
• Textures: number of three.js textures in the scene. A lower count means the scene is using less memory and sending less data to the GPU.
• Programs: number of GLSL shaders in the scene.
• Geometries: number of three.js geometries in the scene. A lower count means the scene is using less memory.
• Vertices: number of vertices in the scene.
• Faces: number of faces in the scene.
• Calls: number of draw calls on each frame.
• Load Time: how long it took for the scene to start rendering, in ms.
• Entities: number of A-Frame entities.
